Energy efficiency Virtualization
APC by Schneider Electric – Pjilip Fischer – March 2011
● Increased CPU utilization and efficiency● Typical server utilization rate: ~10-15% (usually higher in storage)
● Virtualized utilization rate: Up to 80%
● Server consolidation ● Decreased need to purchase additional servers
● Increased rack space● Reduced data center space requirements
● Improved continuity and disaster recovery● Virtualized servers can be mirrored in case of failure
● Reduced labor costs ● Easier hardware provisioning and maintenance
Virtualization Benefits
APC by Schneider Electric – Pjilip Fischer – March 2011
● Virtualization always increases efficiency
● I don’t need to worry about power and cooling when virtualizing
● High density and high efficiency cannot coexist
● Virtualization requires high density data centers

Impacts and Challenges of Virtualization

Virtualization: Good for Cooking Dinner?
Higher Densities per rack create Power and Cooling Problems

Challenges to Maximizing Virtualization
APC by Schneider Electric – Pjilip Fischer – March 2011
Constant loads Stable cooling Migrating high-density loads Unpredictable cooling
BEFORE virtualization AFTER virtualization
Challenge 1:Power Density
•Virtualization instantly drives up power densities at a rack level
•Cooling challenge•Per tile airflow of 300-600 cfm hard to maintain
•Raised flooring and perimeter cooling not the right choice
•Power distribution Challenge•Need new breakers
•New voltage supply levels
•Weight-bearing capacities should be reviewed
APC by Schneider Electric – Pjilip Fischer – March 2011
Challenge 2:Dynamic Power/Cooling Is Mandatory
●Use power-capping with integration of DCIM and VM
●Need cooling system which can dynamically regulate cooling capacity
●DCIM works with VM Manager allowing for informed decision making

Challenge 3:Rapid Scalability Becomes Critical
●Speed of provisioning new "servers" is super fast
●Need agile infrastructure to cope●Capacity management tools for real-
time monitoring and analysis of information about the three essential capacities of the data center:
●Power●Cooling●Physical space
●Stranded capacity = inefficiency

Challenge 4:Availability Architecture Changes
●Data center physical infrastructure should be designed based on the fault-tolerant nature of the virtualization IT model
●Redundancy is less important to physical infrastructure if IT is highly fault tolerant
●Consider N+1 architecture
APC by Schneider Electric – Pjilip Fischer – March 2011
Challenge 5:Virtualization Impacts Operations
●Initially, virtualization leads to consolidation….but be prepared for rapid growth
●Rapidly changing demand and capacity requires tools to keep operations up and running
●Physical servers are now a capacity element just like power and cooling
●Supply while traditionally being just power, cooling and physical space now includes servers and the network bandwidth

Why Integrate Virtualization and Datacenter Management?●Automate
● Virtual machine migration when an issue arises in the physical infrastructure
●Solve the issue● Of keeping virtual machines running during physical infrastructure
incidents
●Map dependencies● Of physical servers to physical infrastructure
●Ensure your enterprise applications● perform with the highest availability and performance
●Build up business continuity● through improved disaster recovery solutions and deliver high availability
throughout the datacenter

DCIM Definition
●A data center infrastructure management (DCIM) system collects and manages information about a datacenter’s assets, resource use and operational status.
●This information is then distributed, integrated, analyzed and applied in ways that help managers meet business and service-oriented goals and optimize their datacenter’s performance.
●In practice, DCIM systems may vary widely in focus, and complete solutions are likely to consist of a framework or suite of products, from one or many suppliers, that are designed to interoperate or complement each other.
●The close interworking of IT and mechanical/electrical systems will increasingly lead to the deployment of solutions that span data-center facility infrastructure, physical IT assets, and virtual IT assets.
